The size of the RadMenu placed in the DropDownContent of a RadSplitButton is incorrect when using the Fluent, Crystal, Visual Studio 2019, or Office 2019 themes.

The Visual Studio designer pops up and gets the keyboard focus while editing the menu items in XAML.

RadMenuItems that are not top-level ones are currently not visible at design time. A possible workaround is to set the IsSubmenuOpen property to True to be able to show them.

Available in LIB version 2017.3.1113, it will be also available in the R1 2018 Release.

Add the HintText property with the same appearance as in UI for WinForms.

Enable using checkable item with subitems.

Implement out-of-the box RadioGroups for RadMenuItems.

Provide mechanism that allows the RadMenu to stays open when it lose mouse capture

Available with the R3 2016 SP1 release. 

If RadMenuItem has command attached and the command's CanExecute method returns false, RadMenuItem will be disabled. In case RadMenuItem is inside RadMenuGroupItem, it is not disabled (the command is not invoked, the problem is just visual).

Available in LIB version 2015.3.1019, it will be also available in the 2015 Q3 SP1.
